They did it in the RRA arc too. Hell a Pirate Robot was stronger than Krillin. It's not out of the ordinary.

I don't have a problem with it since DB was still focus on human capabilities. Freeza is the strongest in the whole galaxy or unniverse along with Goku and Dr. Gero just made a two robots to surpassed them? No wonder why these Androids were rejected as a main villains and forced Toriyama to create Cell who is a lot of credibility surpassing Goku and Freeza.

apparently in GT you lose your halo the moment you descend from heaven to hell, and when you escape Hell you also magically are alive again despite that contradicting every known fact about death in the original manga

That even goes against fucking DBZ movie 12 which they clearly ripped off big time when they made this piece of arc along with Z filler which showed villains having bodies in Hell in the first place, but I guess that's why even GT fans usually only defend this arc if they like sucking 17's cock
